We go to the gym for various reasons.  It could be to lose some pounds, develop muscles or simply to maintain a healthy working body.  Or it could also be because lately you’ve been squeezing and jumping into your jeans to no avail.

Now you can slip into your jeans with the magic of Skinny Jeans Workout.  As the name implies, this routine will cut the fats from your core, butt, and thighs–or as instructor Lisa Grimmer told CNN, “anything placed in your jeans.” The Skinny Jeans Workout will have you zipping up at the drop of a hat.

Jessica Ordona, who takes the class and hates the way her stomach hangs over her jeans, tells CNN:

“It’s different than your typical workout class,” she says. “It’s not high-impact cardio, but you’re sweating the whole time because you’re working every muscle group.”

The exercises work by tightening up the core muscles, improving posture, and even strengthening the shoulder girdle. Obviously, spot training doesn’t work miracles, but regulars say they’re dropping a pant size or two in just a few months from the twice weekly workout.

Now isn’t this good news for you? No need for alterations and no need to buy a bigger size; there’s a certain exercise that will get you slipping smoothly back into your favorite denims in no time.
